Chapter 7: CTRIO Workbench, I/O Map
I/O Map with an H2-PBC or T1H-PBC Profibus DP Controller
When using the CTRIO(2) module with an H2-PBC or T1H-PBC native
Profibus addressing will be displayed in the I/O Map as shown below.
For the T1H-PBC, the first two output bytes of memory are automatically reserved
for the Hot Swap base-rescan feature. The H2-PBC does not support the Hot
Swap feature.

Note that output bytes 0-1 are reserved
for the Hot Swap base rescan feature.
Creating an Offline File for H2-CTRIO(2)/T1H-CTRIO Module
For the T1H-PBC, enter a 2 byte Output Offset to accommodate memory used by the Hot
Swap base-rescan feature. This does not apply to an H2-PBC system. The example shown
below assumes the T1H-CTRIO module is the first module in the system.
The CTRIO(2) modules consume 44 bytes of input memory and 52 bytes of output
memory. The maximum amount of I/O memory per H2/T1H-PBC station is 244 input
bytes and 242 output bytes. You may
need to refer to the Profibus User
Manuals (H2-PBC-M / T1H-PBC-M)
for information on bytes used by discrete
and/or analog I/O modules in order to
determine the appropriate Starting input
and output byte offset addresses for the
CTRIO(2) module.
For the T1H-PBC, enter a 2 byte Output Offset to
accommodate memory used by the Hot Swap baserescan feature.
